Can a Wii Mod chip allow the ability to play American games on the Japanese Wii?

Well, I couldn't find any Wii's in any stores. So, my parents have a friend who lives in Japan, and they wired the money to them to buy two Wii's: one for me, and one for a friend. But, they (more of my mom) didn't know that the Japanese Wii console couldn't play American games. And we can't read Japanese!!

So, will a Mod Chip make the Japanese Wii console allowed to play American games?
